1 Claim.

This invention rel-ates to improvements in assembled partitions forcardboard boxes.

The partitions or dividers now generally used in cardboard boxes are ofthe notched or slotted varieties, and the several notched pieces need tobe carefully set together by hand and inserted in the box; all of whichrequires tedious and time consuming labor, thus considerably enhancingthe cost of producing the cells in the boxes by the use of suchpartition means.

It has been attempted to obviate such notched partitions, by securingseveral plies or strips of cardboard together, as by the use of glue,and then bending the wings upon score lines outward from the main centerstem, as is indicated in the patent to Gemmill, #2,105,645. However,that form requires score lines whereon to bend the Wings, and thusnecessitates an extra scoring operation; and furthermore, the main stemmust thereby also consist of many superposed plies or layers, requiringhalf as many layers as there are cells in the box, so that such formmakes the central stem too thick and requires too much material,especially where a large number of cells are required in the box.Moreover, the glue used in such forms for securing the strips togetherin those partition units tends to give oiT odors, etc., which becomesinjurious to candy and the like when packed therein.

The main object and purpose of this invention is to provide an efiicientpartition means for cardboard and paper boxes which can be readilymanufactured and quickly and conveniently inserted in the box, and isadapted for producing any desired number of cells, at a minimum of st.

A more particular object of this invention is to provide partition meanscomprising several units, each of which has several sections or wingsfirmly secured together, so as to avoid the use of slotted pieces whichrequire considerable time for combining and inserting them in the box;and to have the wings of each unit seamed together so as to be readilybent apart on the seam line, to avoid the use of glue and to obviate theneed of any extra score lines whereon to bend the wings apart.

A further object of this invention is to provide an improved method formaking such partition units, so that they can be readily manufacturedand quickly installed in the box, at a minimum of cost for material andfor labor; and which will provide flexibility so as to readily produceany number of cells desired in the box.

These and various other objects and advantages are attained with thisinvention, as will become apparent from the following description, takenin connection with the accompanying drawing illustrating this inventionin its preferred form of construction, it being apparent that otherforms and modifications may be resorted to for carrying out the objectsand purposes of this invention.

In the drawing:

Fig. 1 is a plan View showing part of a pair .of superposed sheets ofmaterial seamed, together along the middle line, which are then cutacross the seam into strips to provide the partition units.

Fig. 2 is a plan view of a partition unit in its flat shape.

Fig. 3 is an edge view of such a flat unit.

Fig. 4 is a perspective view of a partition unit with its wings unfoldedalong its seam line, ready for use.

Fig. 5 is a plan view of a box having several of my partition units setin place therein to provide the cells.

Fig. 6 is a section-a1 View thereof, taken on line 66 of Fig. 5.

The drawing illustrates this invention in the preferred form ofconstruction, and it discloses the preferred method of making the unitsand setting them in place in a box, for providing the desired number ofcells in the box.

In carrying my invention into effect, in making this improved partitionunit and utilizing it for providing cells in a box, two layers or sheetsl0 and II of material, preferably fibrous material, such as cardboard,paper or the like, are laid one upon the other and are secured togetherby running .a seam l2 along their middle line. This is readily andeconomically done by means of a machine in the shop; and an ideal manneris .to employ tWo sheets of such material which are superposed on aroll, and run these superposed sheets together from the roll thru thesewing machine, thus conveniently securing the pair of sheets togetherby the seam.

This united pair of superposed sheets is then cut across, laterally, asindicated by the dot-anddash lines 13, shown in Fig. 1 of the drawing,to provide the partition means or units [4 of the desired size, each ofwhich consists of two strips [5 and I6 having part of said seam l2extending along the middle cross line thereof, substantially as shown inFigs. 2 and 3. This cutting is preferably done by laying a number ofsuch pairs of seamed sheets upon each other and cutting them togetherinto the desired size by means of a cutting machine in the shop.

These partition units are then in their flat shape, and can thus bereadily stored and shipped; and when it is desired to use the same thesections of said strips [5 and. [6 are then conveniently bent apart onthe seam l2, so as to provide four wings or sections l5, l5, l6 'andI6", which extend substantially at right "angles to each other, as shownin Fig. 4. The seam I2 has thereby provided the securing means along themiddle line of the strips for securing them firmly together, and it hasalso provided a score line or means whereon the four wings are easilybent apart, and without any necessity of providing extra score lines orrequiring any extra scor-' ing operation.

These partition units with their wings bent apart are next readily setinto the box [1 whenever desired for use, and they areso arrangedtherein'that a wing of one unit overlaps a wing of an adjoining unit,and so as to provide substantially rectangular cells in the box, asshown in Fig. 5, ready to receive the 'articles'therein.

With this invention I provide an improved and economical partition meansand manner of manufacturing it, so that it can be readily constructedand quickly set in place in the box, all at a minimum of cost. v Imoreover avoid the lengthy and tedious labor required insetting'together the customary notched type of partition means in thebox; since with this method I canrun two superposed sheets from a rollthru the sewing machine, and thus readily secure them together. I alsoavoid the troubles encountered with the other form, which requirestriple and quadruple layers in a unit, and further requires the doublesteps of first gluing the sheets together and then also providing scorelines whereon to bend the wings apart.

This partition means furthermore provides flexibility, as the severalunits can be readily set together in the box, with the adjoining wingsoverlapping, as shown in Fig. 5, so as to conveniently provide anynumber of cells desired in a box, by the simple use of this oneinexpensive form of unit.

I claim:

In a rectangular cardboard box, a plurality of partition units, eachconsisting of a pair of strips of fibrous material which are securedtogether by a line of stitches extending across the middle thereof,providing four alike wings which are readily bent apart on each stitchline and extend substantial-1y at right angles to each other, said unitswith their wings so bent apart being positionedin the box to have atleast each of two wings of each unit substantially fully overlapped by awing of an adjacent unit, each pair of overlapped wings being paralleland in face contactme; relation, thereby readily producing a selectednumber of similar sized substantially rectangular cells in the box.
